I will keep this review spoiler-free. I saw this in the cinema today and it was not what I would have guessed in any way (nor did it resemble the works some commenters have mentioned).

All the way through this film had me fully engaged. It didn’t rely on any cheap jumpscares or implausible elements that would lead to plotholes or break immersion; if anything, what’s scary is the plausibility. There was some serious attention to detail from the cast and creators, which lead to me well and truly enjoying the experience.

The actors all nailed their parts, the soundtrack was unobtrusive but used perfectly when it had its moment (a hard feeling to describe but that moment was perfect). I was left with two small questions that would likely be answered by being better at Japanese, however I can also say I was left deeply satisfied with what I watched.

A little point of caution is that this film is graphic - the murder cases aren’t glossed over and there’s injury detail.
